mikalv / accrete.js

Planetary system formation simulation in your browser, or on the server.

ACCRETE v.1.0.0

Planetary system creation simulation in the browser, or the server.

The codebase has been completely reimplemented from scratch in a form that more closely resembles that put forth in the original Dole paper.

Usage

Building

$> npm install && npm build

Browser

<script src="accrete.min.js" />;
const system = new Accrete.StarSystem();
system.create();

const planets = system.planets;

Node

import Accrete from "Accrete";

const system = new Accrete.StarSystem();
system.create();
const planets = system.planets;

Goals

• Organize the codebase into a more modern, and JavaScript friendly structure.
• A full build process for Browser/Node scripts and modules.
• Implement a good chunk of StarGen's features.
• Live WebGL view and screenshot options for created systems.
• Other cool things to take advantage of this amazing program.

History of Ac(c)rete

Accrete.js is an implementation of the awesome planetary system simulation algorithm, Accrete in JavaScript. Originally published* and partly programmed (via FORTRAN) by the amazing Stephen H. Dole. Almost a decade later Carl Sagan and Richard Isaacson refined Dole's model -- which shortly thereafter was also implemented in FORTRAN, and again elaborately and academically published by Martin Fogg in his paper "Extra-Solar Planetary Systems".

The late 80's came and Matt Burdick brought this priceless program to the masses (via Turbo Pascal and C). Since then, many versions of Accrete have popped up around the internet, adding varying degrees of planetary specifics – the most notable (and ingenious) being Jim Burrow's implementation StarGen. Ian Burrell's Java port is another great example (and was of great help on Accrete's previous implementation).
